Manual
Series A3 & A4
The Sensocon A3 and A4 series of differential pressure controllers provide control
of low differential pressure applications for air and other compatible non
combustible gasses. These instruments have a large LED display for pressure
indication, a LCD or OLED display for programming and additional LED’s to
indicate % of output, setpoints and alarm status. The instruments are fully
programmable from the key pad face or by utilizing the Opti-Link™
communication port for no touch programming. Options for the instruments
include a 4-20 mA output, and improved accuracies. There is also a low cost
weatherproof cover available for outdoor applications.
